Cerego Lab Report

Station one: Station one shows that when a small piece of magnesium metal is placed over the flame of the Bunsen burner, the magnesium metal ignites, giving off a bright, white light. Once the flame has extinguished itself due to the lack of fuel, the magnesium metal turned from a metallic strip to a crumbled white powder. It can be decided that station one is a combination (redox) reaction, as a new product is synthesised by the combination of two reactants. The reactants, magnesium and oxygen gas in the air bonded together to form the product of magnesium oxide.

Chemical changes occurred in five out of the eight experiments completed in this lab. Although the main focus of experiment two was

In this experiment, we learned about stoichiometry, empirical formula, molecular formula, polyprotic acids and bases, metathesis reactions, and moles.

The experiment is to observe a variety of chemical reactions and to identify patterns in

When looking over my results, I found that the pH level increased from a neutral pH to a basic level of pH. The Miracle- Gro fertilizer that I used is supposed to have a pH of 7. This surprised me because I would think that adding a 10% fertilizer solution would make the water acidic. I thought that the fertilizer would be more acidic because when we learned about rivers, we found out that acid rain decreased the dissolved oxygen levels; also, Eutriporication results in low dissolved oxygen levels. Therefore I believed that the fertilizer would be acidic because of my background knowledge of dissolved oxygen in water. Regardless, the basic water killed the algae, elodea plant and the snails in the water. I also thought that eutrophication would occur in the water when

The materials needed for this experiment included test tubes, a test tube holder, the unknown compound #202, 35mL beakers, gloves, safety goggles, ethanol (to clean equipment), stirrer (to mix solutions), the 15 possible compounds that are provided, pH strips, distilled water, wooden splints, spatula to get out unknown compound #202, waste bucket, Bunsen burner, graduated cylinder, 500mL beaker for the waste, plastic dishes to measure out compound and the scale.

The mole is a convenient unit for analyzing chemical reactions. Avogadro’s number is equal to the mole. The mass of a mole of any compound or element is the mass in grams that corresponds to the molecular formula, also known as the atomic mass. In this experiment, you will observe the reaction of iron nails with a solution of copper (II) chloride and determine the number of moles involved in the reaction. You will determine the number of moles of copper produced in the reaction of iron and copper (II) chloride, determine the number of moles of iron used up in the reaction of iron and copper (II) chloride, determine the ratio of moles of iron to moles of copper, and determine the number of atoms and formula units involved in

As the first written assignment (due January 22, 2016) for the Junior Chemical Engineering Lab (CHE 352) taught by Professor Burrows, I will be endeavoring to provide a superior reflection of my personal standards and assignment quality. Although this assignment will be submitted to Professor Burrows, the individual that this assignment will benefit the most is me. This work will allow me to focus on data research, data analysis, professional writing skills, and advance my knowledge concerning the technical requirements of this course; thus, directing me towards a higher level of professional document writing and presentation. Through completion of this assignment, the guidelines of Professor Burrows will prepare me intellectually for the challenges of future written projects in this course, thus making my material easier to read and evaluate.

Every unit is a challenge and this one was not the exception. I learned a little bit more about java programming it got a little more complicated this time which in a way is good because it keeps me engage to continue learning.

Desert animals experience large daily variation in environmental temperature, with high temperatures during the day and low temperatures during the night. What effect do you expect a drop in temperature from 25°C to 0°C would have on the heart rate of an ectotherm (e.g. a lizard) compared with an endotherm (e.g. a fox)? Explain your reasoning? As the Lizard is an ectotherm, when the temperature decreases, so does the body temperature as it depends on external heat sources.

In this study, we designed and examined the effects of different degrees of soil moisture levels on the distance travelled of Cepaea nemoralis. Our experiment showed that the average distance travelled of Cepaea nemoralis was higher in moister levels of soil. This was the case in both Trials 1 and 2 and statistical analysis showed that both Trials were statistically significant (See Figures 1 and 2). Through various research and previous observations, our prediction was that the Cepaea nemoralis would move a longer distance in moister levels of soil. Higher levels of soil moisture were expected to cause more movement because the mucus produced by the glands helps them move more efficiently, without hurting themselves (Why Do Snails Leave Slime

4. Determination of Galacto-oligosaccharides The techniques used for the determination of GOSs should be simple, rapid and precise. So, range of methodologies have been used to determine the GOSs including, gas-liquid chromatography, thin-layer chromatography, high-performance liquid chromatography and other related techniques such as: Electrospray Ionization-Mass Spectra, Nuclear Magnetic Resonance, UV-spectrophotometry, High pH anion exchange chromatography with pulsed amperometric detection (Table 3). 4.1 High Performance Liquid Chromatography

I found all of our simulations very interesting today. I gained an enormous amount of information which I am sure will enhance my skill performance. Our instructor was very helpful in explaining fetal monitoring and how to interpret the strips. I thought that she did an amazing job explaining how to read the strips and answering the questions we all had. I feel more confident about this material than I did prior to coming to clinical. I would have to say that learning more about this is one of

While there were a few successful workshops, there were also failed workshops. I believe that we had more bad workshops than good ones. On more than one occasion, my students have come to workshop with no resources and no motivation. One instance that I can recall is the week after Spring Break. Before Spring Break, the students were instructed by
